## Motivation

Bringing emails to the terminal is a pain. The mainstream TUI, (neo)mutt, takes
time to configure. The default mapping is not intuitive when coming from the
Vim environment. It is even scary to use at the beginning, since you are
dealing with sensitive data!

The aim of Himalaya is to extract the email logic into a simple (yet solid) CLI
API that can be used either directly from the terminal or UIs. It gives users
more flexibility.

## Installation

```bash
curl -sSL https://raw.githubusercontent.com/soywod/himalaya/master/install.sh | bash
```

*See [wiki section](https://github.com/soywod/himalaya/wiki/Installation) for
more information.*

## Configuration

```toml
# ~/.config/himalaya/config.toml

name = "Your full name"
downloads-dir = "/abs/path/to/downloads"

# Himalaya supports the multi-account
# Each account should be inside a TOML section
[gmail]
default = true
email = "my.email@gmail.com"

imap-host = "imap.gmail.com"
imap-port = 993
imap-login = "test@gmail.com"
imap-passwd_cmd = "pass show gmail"

smtp-host = "smtp.gmail.com"
smtp-port = 487
smtp-login = "test@gmail.com"
smtp-passwd_cmd = "pass show gmail"

[posteo]
name = "Your overriden full name"
downloads-dir = "/abs/path/to/overriden/downloads"
email = "test@posteo.net"

imap-host = "posteo.de"
imap-port = 993
imap-login = "test@posteo.net"
imap-passwd_cmd = "security find-internet-password -gs posteo -w"

smtp-host = "posteo.de"
smtp-port = 487
smtp-login = "test@posteo.net"
smtp-passwd_cmd = "security find-internet-password -gs posteo -w"

# [other accounts]
